Status:Open Resolved:
Product:iOS SDK Product Version:iOS 9 Beta 2 (13A4280e)
Classification:Other Bug Reproducible:Always
 
Summary:
After registering a callback with SCNetworkReachabilitySetCallback with a reachability created with a domain , starting with iOS 9, it will not be called on initial launch if launched in airplane mode. Launching with a network connection behaves as expected

Steps to Reproduce:
Register with SCNetworkReachabilitySetCallback in code
Launch device in airplane mode

Expected Results:
Callback would be called with offline flags, as it is in iOS versions prior to 9.0

Actual Results:
Callback not called initially

Version:
iOS 9 Beta 2 (13A4280e)

Notes:
Sample project: https://github.com/maxgoedjen/OfflineLaunchCallback

Configuration:
iPhone 6 Verizon

had same issue on OSX 10.13, xcode 10.1 apparently i was scheduling the callback not on main thread and the callback had no thread to return to. fixed by dispatching to the main queue

also not called on network change in the background

for me it also doesn't seem to get called for a VOIP app in the background where the network changes. no callback even though on iOS8 is did work.
